“…The recorded emission levels for the biofuel are comparatively low and reduce with increased engine speed until at 2200 rpm they increased. This has been observed for other biofuels [10] for reasons related to the oxygen content of the fuel. Studies by Monyem etal [11] show that unburned hydrocarbons generally emanate from the regions in a cylinder where there is a poor fuel/air mixture to such a high extent that the ratio is past the combustion limit.…”

“…The higher exhaust temperature of the Croton SME is indicative of lower thermal efficiency, less of the energy input in the fuel was converted to useful work, and the remaining heat is given out as exhaust temperature [6]. Puhan [8] considered that the high exhaust temperature results from longer ignition delays that produce a higher exhaust temperature but AlWidyan et al, [10] stated that the higher exhaust temperatures may result from higher combustion temperatures. The emissions of Carbon Monoxide (CO) from the test engine when fuelled with the diesel and the CME and its blends are compared in figure 6.…”

“…Al-Widyan et al 48 estudando o potencial do biodiesel para substituição do óleo diesel obtiveram resultados que indicaram que as diversas misturas éster/diesel estudadas queimaram com maior eficiência e com menor consumo específico de combustível, resultando, portanto, em maior eficiência térmica do motor. Além disso, as misturas produziram menos monóxido de carbono que o óleo diesel.…”

“…The higher density and kinematic viscosity of fuels result in the injection of a larger mass of fuel to the engine for the same fuel volume [12]. Again, the greater the viscosity of the blend, the less the leakage in the fuel pump [13,14]. A higher mass flow compensates for the lower heat energy content of blends [15].…”
